\[\left( x - \frac{4}{5} \right) + \frac{1}{30} = \frac{1}{6} - \frac{1}{10}\]
\[x - \frac{4}{5} = \frac{1}{6} - \frac{1}{10} - \frac{1}{30}\]
\[x = \frac{1^{\backslash 5}}{6} - \frac{1^{\backslash 3}}{10} - \frac{1}{30} + \frac{4^{\backslash 6}}{5}\]
\[x = \frac{5 - 3 - 1 + 6}{30}\]
\[x = \frac{7}{30}.\]
